It’s a battery, they can probably forgo a lot of the usual testing since it’s only necessary to match voltage performance requirements.
In theory, it could also be used to replacing existing vehicles batteries as well.

They can’t bypass certifications
They’ve also been pushing hydrogen and not working on BEVs while everyone else was working on BEVs
I like your optimism, but this is just marketing fluff that won’t come to market on that timeline
I don’t know if the journalist didn’t understand, or Toyota lied, but it’s not happening by 2028

What certification does it need other than be certified by Toyota for use?
You’re right it’s unlikely to happen, but not for any technical or testing reasons like you claimed. If Toyota wants to make it be able to replace existing ones, it’s entirely possible. There’s nothing stopping them other than the battery technology not being able to be the same formfactor for performance.

Engineer in the automotive industry here. Vehicles need a ton of certification by tons of different governments and face very strict regulation.
Just a battery alone is going to be subject to lots of EMC emissions and interference tests. Then you have the capability to survive crashes, fail operational requirements, how does the battery fail (does it explode or just disconnect itself?), etc. etc. These are all dependent on the chassis the battery is in, so they can’t just swap it into an existing chassis and say “Oh it worked with battery A, it’ll work with battery B.” Unfortunately the requirements are just way too strict for that.
Additionally I can’t go into details but the sentiment others are echoing of “If it’s coming in 2028 they should have a functioning prototype” are true in my experience. It takes several years to design and release a car, and when you’re introducing a new battery tech or drive train or similar changes it takes even longer.

Humor me. It’s possible with the batteries we already use, why would this be different?

Then Toyota has some magic power that all the other car companies I work with don’t
I know Tesla plays fast and loose with NHTSA regulations, but I doubt Toyota will
This battery technology will have to pass safety inspections, just as Li-ion

Test it in existing vehicles, can even do it discretely without the public knowing.
Why would it be magic to make a replacement battery, and how would they be playing fast and loose?
